Christopher Smith created GROOVY-9822:
-----------------------------------------
Summary: StackOverflowError in STC
Key: GROOVY-9822
URL: https://issues.apache.org/jira/browse/GROOVY-9822
Project: Groovy
Issue Type: Bug
Components: Static compilation
Affects Versions: 3.0.6
Reporter: Christopher Smith
This appears similar to GROOVY-9565, but it's happening in a context that is
generics-free as far as I can tell. I have the following pair of files, where
the graph-related types are from TinkerPop:
{code:groovy}
@CompileStaticinterface GremlinAccess {
GraphTraversalSource readOnly()
GremlinSession session()
interface GremlinSession extends AutoCloseable {
GraphTraversalSource traversal()
}
}
{code}
{code:groovy}
@TupleConstructor(defaults = false)
@CompileStatic
class GraphObjectGremlinAccess implements GremlinAccess {
final Graph graph
@Override
GraphTraversalSource readOnly() {
graph.traversal().withStrategies(ReadOnlyStrategy.instance())
}
@Override
GremlinSession session() {
new PlaceboGremlinSession()
}
private class PlaceboGremlinSession implements GremlinSession {
@Override
void close() {}
@Override
GraphTraversalSource traversal() {
graph.traversal()
}
}
}
{code}
The first file compiles without problem. The second file triggers a stack
overflow, looping the four lines from 1870 to 1882:
{code}

{code}
I'm attempting to trim down the example.
